THE SENSOR OF TEMPERATURE OF THE ALARM BULB COOLING THE LIQUID / SWITCH

Both sensors are established in one module.

Identification of plugs of the sensor of temperature okhdazhdayushchy the liquid / sensor of an alarm bulb (3-штырьковый I will corrode connections)

1. Plug of an alarm bulb
2. Weights plug
3. Plug of the sensor of temperature

Identification of plugs of the sensor of temperature okhdazhdayushchy the liquid / sensor of an alarm bulb (4-штырьковый I will corrode connections)

+ – the food plug
With – the plug of an alarm bulb
R–conditioner plug
T–plug of the sensor of temperature

Check

PERFORMANCE ORDER
Check a food and grounding of sensors. Check resistance of sensors at various temperature of cooling liquid. If sensors are faulty, it is necessary to replace them.

Removal

PERFORMANCE ORDER
1. Partially merge cooling liquid.
